In Version 4.0.102 (521) the temperature in the menu bar is usually wrong. If I exit YoWindow and reopen it the temperature in the menu bar is correct.
I have macOS High Sierra v.10.13.5 (17F77). Thank you for any suggestions.

I am editing my question so it is more clear:
I still have YoWindow Version 4.0.102 (521) but I now have macOS High Sierra v.10.13.6 (17G65).
The temperature in the menu bar does does match the temperature in the YoWindow User Interface. For example, the User Interface currently reads 88 degrees Fahrenheit but the temperature in the menu bar reads 79 degrees Fahrenheit.
I just exited YoWindow and reopened it and now the temperature in both the menu bar and the YoWindow User Interface read 88 degrees Fahrenheit.

How did you get Version 4.0.102 running under MacOS High Sierra? I have MacOS High Sierra version 10.13.6 (17G65) and YoWindow crashes when I try to Open it.
